The 1973 Monaco Grand Prix was a Formula One motor race held at Monaco on 3 June 1973. It was race 6 of 15 in 1973 Formula One season.

The race was held on a heavily revised circuit, with a longer tunnel, a new section of track around the new swimming pool on the harbour front, and the Gasworks hairpin replaced by the Rascasse and Antony Noghès corners, the latter named after the founder of the race. The pits were also moved back to the start-finish straight, on a wider pit lane.

The race was won from pole position by Scotland's Jackie Stewart, driving a Tyrrell-Ford. In the process, Stewart equalled the record of 25 Grand Prix victories set by his friend Jim Clark. Brazil's Emerson Fittipaldi finished second in a Lotus-Ford, with Swedish teammate Ronnie Peterson third.

This was the first race for future World Champion James Hunt, driving a March-Ford entered by Hesketh Racing. Hunt suffered an engine failure in the closing stages of the race, but was classified ninth.
